Just got some time to check the comments. Some of you guys are giving me a hard time, so let me clarify.

1. I make arguments about technology, sometimes my views are not conventional, but always I back it up with evidence. (almost always) One of you guys say SpaceX does not bring things down from Orbital velocity, this is wrong, Dragon capsule is brought down from orbital velocity, and some of them have been reused, that is how advanced SpaceX currently is. And I disagree with statements like "3d printing isn't that much of an improvement".2. I agree with some of you guys saying its unfair to compare the shuttle with crew dragon, but I do think its fair to compare the shuttle with Falcon 9.3. I will put more time in typos, this has appeared a few times, apologies. In my defense, I am doing all of this by myself and it is hard.

Finally, it is hard to make arguments on YouTube, If I wanted no bad comments, I would have just copied the information from Reddit and Wikipedia to this video and everything will be factual, but that is not what this channel is about, this channel is about analysis and perspectives.

But I do apologize if I have not made my point clear in the video such as "orbital velocity" thing, I meant spacex has experience slowing things down from orbital velocity, aka Crew dragon. SpaceX also has more experience down from a slower velocity of 8000km/hr

I've never wanted something to be successful so much in my life, that didn't involve myself or people I loved. IF SpaceX is successful, spaceflight will OFFICIALLY be commercialized. That means you or I could sell EVERYTHING we own, and make it to the ISS or an inevitable space hotel...

No. I am sorry. The Dragon is a recovering and catching back up with advancements we have fallen behind with. The space shuttle and Dragon can achieve the different missions. The Dragon can not do what the space shuttle could. So far the Dragon is an transport not the rest of the space shuttle could achieve. Quit bashing the space shuttle in the name of making the dragon seem more than it is. Considering the shuttle was built how long ago. It was built now it would be far better in achieving the missions it was used for beyond taking Astronauts and Cargo to the ISS. Retrieving and repairing satellites was a major plus. Dragon is an dvance throwback to the space capsules we started with. So I hope we progress again.

your english is bad don't listen to what your friends are telling you. your english is barely intelligible. if you stick to one or two syllable words I cahn understand but when you tried more you are a joke.

60’s technology is still alive and well! Shuttle not a glider lie number 1189. All astronauts are still alive living normal lives. But don’t bother Googling it. You can find here on you tube and you will say WTF!

This presentation is appalling and fall short in every way...! Please do effort more on Research!.. don't just copy and paste you trying hard chinese rocket scientist wannabe...! Do away from the vicious copyright infringes of your chinese pirates kind...!🤬🤣😜😡

Wow. Lots of misinformation and flat out mistakes here. Was this video sponsored by SpaceX?

1) It was not the heat tiles that made the STS unsafe. It was the mounting of the orbiter on the side of the first stage. Debris during lift off could, and did, damage the tiles. The STS would have been a lot safer had the orbiter been positioned on top of the launch stack, as in the original design. NASA's lax safety culture during the STS years was also a big factor; Challenger launched when it was too cold and the damage to Columbia during lift off was ignored.

2) Yes the Crew Dragon has touch screen displays and this is not necessarily a good thing. I have a hard enough time controlling my phone with it's touch display. Now imagine using a complex touch only computer in a life shaking space craft, at 5Gs, with a foggy helment and space suits gloves on. Aircraft still use physical switches for a reason, as does the competing Starline capsule; don't be surprised if those screens get taken out for the crewed launch. I would not risk my life to a cool-looking touch screen with no feedback or tactile feedback.

3) Increased computerization is hardly new and is not always a good thing. Computers a susceptible to bit flipping by cosmic rays which is why the Dragon has THREE computers on board to double check calculations. The older, more robust systems in the Soyuz are not so vulnerable.

4) The Soyuz has crew escape systems for every step of the launch, even after the tower is ejected. Crew Dragon is by no means safer or unique, in fact it's only escape system is it's super draco engines. The Soyuz by comparison has independant escape motors in it's tower and fairing, which protects the capsule during ascent. Crew Dragon has no fairing and is vulnerable to damage during ascent.

We're seeing more and more pictures of SpaceX's new Dragon 2 Crew Capsule that will be flying in 2019! One question that comes up often is why does it have fins? Well we're going to explain EXACTLY why it has those fins in today's video!
